Doug,
You Goof...
You posted something else, which everyone could see, then you changed it while I was posting a response. I then had to edit my response because it made no sense to your edited version.
I was going to go with Grade A medium, That's what Mike had in the Baha Benroy and that's what he went with in the Lil' Diner. He highly reccommended it for the dual purpose. If it turns out to be too hard for sleeping, I'll just have to put rocks in his bed when he's not lookin'.
Naaah... I wouldn't play a trick like that on Mike...
I'd really like to figure out a way to stow this memory foam topper to put over the four bench cushions... Now that would be sleeping in comfort!!!
I wouldn't win the fastest bed making contest though...
But I'd still win the fastest bed wrecking contest.
